List of the most common filename extensions used when a game's ROM image or storage medium is copied from an original ROM device to an external memory such as hard disk for back up purposes or for making the game playable with an emulator. In the case of cartridge-based software, if the platform specific extension is not used then filename extensions '.rom' or '.bin' are usually used to clarify that the file contains a copy of a content of a ROM. ROM, disk or tape images usually do not consist of a single file or ROM, rather an entire file or ROM structure contained within a single file on the backup medium.[5] Source.
